As reported by BulbanewsNOW, a Pokémon sales sheet has revealed a Pokémon Black and White Versions 2 Guidebook, due out in the summer, that contains what is being called the "Perfect National Pokédex." It is said to contain all 649 Pokémon, including Genesect, which has yet to be officially revealed. Every Pokémon's Hidden Ability will be featured in this Pokédex. It is scheduled to be released on 11 August.

As yet, it is unclear whether this is a hint that Genesect will be officially revealed in Japan this summer.
